There was no change in turnout among GOP-leaning college graduates, white evangelicals or older voters, said Resurgent.

Worse — for Republicans — is the fact that pro-GOP turnout fell among the party’s critical constituencies.

Turnout fell by 3 percent among white women, 6 percent among white men, 2 percent among Protestants, 9 percent among married voters, and 15 percent among GOP-leaning middle class voters who earn between $50,000 and $100,000.

According to Frey’s AP analysis, the black vote reached 13 percent of votes cast in 2012, even though blacks comprised 12 percent of the electorate.
